Method for raising seedlings of early season rice through plastic trays

Abstract

The invention discloses a method for raising seedlings of early season rice through plastic trays. The method comprises steps as follows: seed soaking for germination acceleration, preparation of soil, management of seedling beds and seedling trays, sowing and seedling management, cloth covering and shed building, seedling field management and lifting of seedlings. Compared with the prior art, the method has the following advantages: the seedling raising cycle is shortened through multiple times of seed selection and microwave treatment; nutrition of each layer of soil in trays can meet growth requirements of early season rice seedlings due to layering of the soil in the trays; non-woven fabric is selected for covering the trays according to the characteristics of the early season rice, changes of temperature difference are reduced, accordingly, the tiller number is increased, and the quality of the seedlings is improved; management processes of seedling raising are specified, the management intensity is improved, the quality of the seedlings is higher, and the yield of the seedlings is increased about 5.3% than that of common early season rice seedlings.

Description

technical field [0001] The invention belongs to the technical field of agriculture and breeding, and in particular relates to a method for growing seedlings of early rice on plastic floppy disks. Background technique [0002] The distribution area of ​​rice planting in China is mainly in the south, and rice production is increasingly concentrated in advantageous areas. In recent years, my country's rice production has gradually concentrated in the middle and lower reaches of the Yangtze River and Heilongjiang rice production areas. At present, the southern rice area accounts for about 94% of my country's rice planting area , The area of ​​rice in the Yangtze River Basin has accounted for 65.7% of the country's total, of which early rice is produced in 13 provinces (regions), and the sown area is relatively large. However, due to the difficulty of controlling the temperature during the sowing period, if it is not properly managed, it will usually cause rotten seeds and rotten ...

AI Technical Summary

Problems solved by technology

However, due to the difficulty of controlling the temperature during the sowing period, if it is not properly managed, it will usually cause rotten seeds and rotten buds. Therefore, at present, seedlings are often raised before cultivation to improve the survival rate of early rice. The plant height grows, but its quality is poor, the dry matter of stems and leaves is less, and the taste of the rice planted is poor. If it is used for industrial grain or grain reserve, if it cannot be used in time, it will often cause waste, and the planting industry will outweigh the gains. Therefore need a kind of seedling raising method that can improve early rice quality
